Yes, A and T are always paired up together. When DNA replicated, adenine and thymine always pair up. However, it's been proven that there is a very very small percentage of extra C, meaning that C and G don't completely pair up because there is about a 0.8% more percentage of C than G. No scientist has been able to prove how or why, though.
Basically, A and T always pair up. Same with C and G, there is just a little bit more of C than G.
Nucleotides are the building blocks of DNA, consisting of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). They are linked together through phosphodiester bonds to form the DNA double helix structure.
yes.
False. In a DNA molecule, guanine pairs with adenine.
Thymine will always bond with adenine, and guanine will always bind with cytosine.
Chargaff discovered that in DNA, there is a 1:1 ratio of adenine and thymine, and a 1:1 ratio of guanine and cytosine. This led to the rule that adenine always pairs with thymine and guanine always pairs with cytosine.
yes.
Yes, there will always be an equal number of adenine (A) and thymine (T) nucleotides in a DNA molecule. This is because adenine always pairs with thymine through hydrogen bonding in a double-stranded DNA molecule, following Chargaff's rule.
Adenine always pairs with thymine in DNA.
The presence of the nucleotides adenine (A) and thymine (T) in a DNA sequence signifies a complementary base pairing, where A always pairs with T.
In DNA, adenine always pairs with thymine.
The 'steps' or 'rungs' of the DNA 'ladder' are complimentary pairs of bases bonded by hydrogen bonds. The bases are Adenine, Thymine, Cytosine and Guanine. Adenine always bonds to Thymine and Cytosine always bonds to Guanine.

There are four nucleotides that make up DNA: Adenine, Thymine, Guanine and Cytosine. There are billions of them that make up one strand of DNA. Adenine always pairs with Thymine and Guanine always pairs with Cytosine. Also, in the Rna during DNA transcription, Uracil replaces Thymine and pairs with Adenine instead.

Nucleotides are the building blocks of DNA, consisting of a sugar molecule (deoxyribose), a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine). They are linked together through phosphodiester bonds to form the DNA double helix structure.
yes.
DNA's long chains of paired nucleotides are made up of four different nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides are paired together in specific combinations (A with T, and C with G) to form the double helix structure of DNA.
Thymine is always paired with adenine in a DNA molecule according to Chargaff's rules. They form a complementary base pair, with adenine pairing with thymine through two hydrogen bonds.
